nitrogen,hydrogen and carbon during heating for Titanium Forgings.This is most effectively done by coating the forging slugs in a liquid glaze or glass which is allowed to dry before heating for forging. The coating fuses at between 500 and 600°C forming a viscous surface which protects the material from contamination. The proprietary liquid glass coatings have lubricating properties which assist metal flow during forging. Some forgers have found that the addition of a liquid based graphite to the die surface further improves die life and metal flow.
